ROOF CONSTRUCTION.

Application filed August 12, 1927. SerialrNo. 212,377.

Also, it is known that moisture Ai'roin the"V steam liberated in such buildin's collects on the roofs and after a while drops down.

It is therefore the main object of this invention to provide means whereby7 the several sections ot a transparent roeil lmay be connected so as to permit a minimum of water or moisture to pass therebetween. I y

A further aini is in the provision or' ineans to catch and carry oli any v'water which should find its way intermediate the sections of the roof and thus prevent the water from drop-V ping down.

yThese several objects, together with others, which will become apparent asy thedescrip'- tionv progresses, are accomplished by the unique construction, combination and arrangement of iiew and siinple'eleinents hereinafter described and illustrated inthe aecoinpanyingv drawing, constitutingan iniportant component of this disclosure, and in which Figure l is a broken perspective view of an embodiment of the invention. as applied Vto a cylindrical tubular beam.

F igure 2 is a similar view showing its ap-. plica-tion to a beam of channel section.

Figure 3 is a like view of the same as applied to a channel beam ot lesser depth. Figure l is a fragmentary perspective view of a slant roof inadein accordance withthe invention.

Referring to the draiving7 the numeral 5 generally designates a plurality of plate glass sections overlapped by inullions 6,' through which pass short rods 7, screw-threaded at f the ends to engage a nut 8 on its upper end engaging the top surface of the inullion, the lower endengaging a beam 9 in the form of a cylindrical tube.

a holder 13 closely following` the contour of a vrof' the holder 13, the resiliently converged tion have been shown and describerhit is not lapping'the adjacent edges ot' vlongitudinal grooves, packing strips dispo 2d vin the grooves to contact the .gutter plaL Engageable onthe rod 7, closely contacting the under-surface oit the plates 5, is av metal plate l0, its longtudinaledges being' rolled toforin gutters 11, the outer edges l2 of which are curled to engage the edges of the gutters and contacting` beam 9, there bcing longitudinal depression la in the holder on each side ot the rod 7, receptive of ruber strips l5 between the depressions and the plate 10.

In Figure 2, instead ofr using cylindrical beam 9, there is substituted a channel-shaped beam 9.0, its upper free edges 21 being` converged to rictionally engagethe inner walls eiids'being spread outwardly by the action or an inverted channel 22 engaging` the lower screw-threaded portion of the rod 7.. 'Y Inl Figurev 3 the beam consists ot a channeled member 25 provided with a transverse pin 26 passing` through the flattened reduced 'lower end 27 of tlierod 7", in thisl case there being. nothroads on the lower end ot the rod.A

l/Vhile the preferred forms ot my invenintendedv that the foregoing be interpreted as limitative, as changes may be u'iade without connicting with the scope oie. the hereto appended claim.

Having thus described my invention, what I claim as new and Vdesire to secure by lietters Patent, is f A water-proof roof comprising a plurality of transparent plate sections, niullions oversections, rods engaging` said mullions and passing interinediate said sectionagutter plates through which said 'rods pass, support plates below said gutter plates, said support plates havin'e)` 33 and a Abeam carryingsaid support platesvand into which said rods are engaged;

ln' witness whereof l have affixed my signature.
